Hilton made an announcement back in April 2014 (access here) that they would be moving away from yearly award category changes and would adjust award categories “seasonally” that seems to roughly every other month/every three months based on the observations.
Hilton HHonors updated its web page for award category changes today. These changes will take effect on January 11, 2017.
